Best E-bike Motor You Can Buy - Grin Tech All Axle Electric Bike Hub Motor Overview | Holmes Hobbies 

*Great **Latest.Bike** . I upgraded the pedals, added fenders and installed a handle bar extension to raise them. Now it’s a pumped out E-Bike. I love it.*

Tabbed torque washers, Hardened steel double torque arms plus lock washers on every build. One spin out 10 years ago and the motor repair taught me a lot.

I got their GMAC motor and am very happy with it. The All Axle motor looks really good if you prefer front wheel hub motors over rear wheel ones. Grin is an awesome company.

Love wheels since I was 1, electric motors came right after that... best combo👍🏻😎👍🏻

Awe man. Wonderful and informative videos ! I'm looking into going electric and I never realized the cons of regular wheels vs this quality e wheel you described. Thank you very much for your insight and shared experiences

I've been a tight nutter and survived that way for two+ years on my etrike before it started spinning out of the fork and ripping the phase leads. This looks like a great solution for front hub builds.

I really like bionx anti rotation locking nut seriously on of the best mechanisms I’ve witnessed for an anti rotation mech

Would love to see some videos of people actually using this motor to get an idea of how powerful it is. Looks really good!

Lots of words and no specs. What kind of torque does it produce, what are the additional stresses it can handle? You mention it's a better design and they do scientific testing but where are the numbers to verify it?

Those motors look really cool. I'll have to check them out. I've built a couple ebikes using the more generic version that you're showing. All the ebikes I've built I've always done a double torque arm setup. I just don't see it practical to assume any other setup would hold up even short-term and especially long-term. It's good to see there's a better option out there. Thanks for the video!

the first 30 seconds had me banging my head on the wall XD

GMAC on a steel touring bike! 52v and it's a dream.

That's a serious freaking hub motor! I'm getting it!

Years back I bought a Crystalyte motor from Grin and it runs with a 52V 18AH battery in a front axle configuration. The motor sits in a steel fork with two torque arms. So far I love it but I will upgrade to the all wheel motor in a rear axle config eventually.

Thank you this was extremely helpful. (First minute was annoying though)😊

The comments are very good. I had my experience with the Aston Rider ebike kit, it came out less than 300usd with lifepo battery and it has been running without problems since I had it more than a year ago

Good talk about weight and reaction torque issues. Not as much about the bearing and shaft which are also critical to me. My project is a quad bike which needs to fit through a 32" doorway. I like the Grin motor because it doesn't stick out past the tire (or looks that way). The quad needs a single side mount with a robust shaft which also cannot stick out past the tire on the outside. This video is 2 years old. I'd love to get an update where we are today and where the technology is going. Thanks for some really good info.

That's exactly what I could not find on the big 2 Internet sites. Thanks.

I mounted an Ebike with one of those kits and on my second ride, I got a bump on the road and the wheel stopped working. I had to push my bike 3 km to my house in the middle of the night. Not a cool thing. This technology really needs to improve. I'm glad you guys are getting into it.

I have an off-the-shelf Juiced CCX and I'm pretty pleased with it- Bafang rear hub running 52v. I'm keen to do an eMTB build in the future, but I suspect I'll do a well sorted factory built one rather than keep sinking $ into experimenting! I want that sweet Specialized Mastermind system.

I must admit, I've had a bit of a fetish for motors myself since I was very young! 😁

Finally found your channel, wow. You are very good on the tube, man. I always knew you would do well, you are a very tallented builder, proud of you JRH.

I need one 😀👍👍👍 thanks for the tutorial.

I’ve been using Goldenmotor Magic Pie v5 and Edge Motor’s on all my builds. I’ve done 5 so far with the oldest built in 2016 still going strong. I like a super clean cockpit so the only thing on the bars is the thumb throttle. Since it’s throttle only I can use any brakes. Some bikes like the oldest uses no torque arms because the kickstand on one side and the derailleur on the other side are heavy steel and so far never had a problem even at 25amps with 52v battery peaking at 58.8v. Another MagicPie-V5 needs 2 Grintech v4 torque arms ir it will spin I the rear dropouts. The edge motors are smaller and have had years with no trouble and no torque arms in aluminum rear dropouts. All these have strong regen and are about $400 usd from Goldenmotor.ca or Goldenmotor.bike. I love that the controller is built into the wheel so I get the cleanest build that’s a regular bike with a throttle for whenever you feel like using it. These are commuter type bikes so nothing fancy. I’d love to build something crazy but the costs add up quickly. Love the videos!!!

Hey man loved the video very informative. I'm working on a specialized big hit and was considering a mid motor pedal assist conversion, this vid came up and I'm considering a front motor now 😂 I need to replace the bottom bracket anyway though

I'm so glad your into e bikes. I always check your RC videos for great info I can trust. Now I'm building an ebike out of a Norco Shore and this is perfect. Except I want rear drive. Or maybe front and rear for muddy snowy conditions. ⚡⚡👍

I have been using my own torque arms for a few years. Easy to make your own using 9-12mm (depending on Adel size)box end wrench with a hose clamp and bolt.. Bolt goes throu round side of box end wrench. Open end of wrench goes on axle.. Hose clamp to frame or fork

The C3Strom Bike I own has no Spokes, just a Rim. Less noise and maintenance regardless of it being heavier. There are definite pros and Cons but I just wanted something Stable and worry free, rugged and reliable. I only wish the Brake pads lasted longer and were more robust. I think there's so much room for new designs for Ebikes though. A dedicated Frame(bike) for that type of wheel wouldn't be too much to ask at all in my opinion. Even if it's just a matter of Sourcing Parts and Machining in a Batch Scale. Similar to what LunaCycles does. I'd buy all the Ebikes if I had the cash😝 Love it! The Video makes so much Sense in justifying design from what I can see and know about through my very limited experience. 👍😎🙏

Hi there. I buy steel drop outs bolted to the aluminium frame working great for 2ys now. Thanks.

You should re-consider your use of close-ups, and know the exact difference in the failure rates of the two types of torque transfers.

Very comprehensive review and in-depth approach to your explanation! Good job.

I think Grin is a great company that is moving the ebike industry forward. I would like to see a smaller lower torque version of this motor for street or commuter bikes that run higher speeds and don’t need a ton of torque.

we recently had a problem putting motor because bike was thru-axel. thru-axle solution is great

Great videp❤

Maybe not the best place to ask, I bought a Kickbike Cross Max 20D and was wanting to put a hub motor on the rear as I understand putting one of the suspension fork is frowned upon. Problem is, it's a strange hub width on the rear that is only about 72mm wide. Is that a hub motor that is out there that would fit? I'm sure I can source it out to 75mm if needed.

How many watts is this motor rated for? Is is more powerful than a 3000w hub drive you can buy off of allibaba?

we finally worked out how to modify these grin all axle motors with liquid cooling and using fast wind wind version with 84 volts these motors should hit the close to 100kms per hour .ive still got abit of saving to do here in australia ,they cost alot to buy them here close to 1000 au dollars i think

Nice video but.....question: how come you.ve opened a greentec motor but on the inside is only the rotor and the outer shell. However the Neodymium magnets are nowhere to be seen ?

I just converted a 26” Cannondale M700 frame with Pepperoni fork to a 500 w 36v front hub motor. I bought a torque arm but sent it back because I guess my nuts are tight enough. It’s racking up some hilly miles with no problems.

There is no mention at all of what battery is needed to drive this?

I was just reading about the Grin 'all-axle-hub-motor" last night, I have an old "Giant" frame that I converted over about12 years ago used a crystallite 407 in the rear wheel, worked ok when the SLA batteries would take a charge. The front suspension fork is an old "Judy Rock Shock" and I am thinking that if I can come up with the funds necessary, I should probably get a whole new package. The fork does have mounts for the disk calliper the rear brake is of course V-brake. It does seem that the folks at Grin have this motor nailed down, expensive yes but well worth it I figure.

I have a 48 volt 500 watt hub motor mounted in the front wheel of my two wheeled recumbent, and yes I use a torque arm, and I've never had a problem.. But then again, since it is a Direct Drive/Magnetic motor, it does not spin up as fast as say a geared hub motor. On the plus side I have a maximum load limit of 600 pounds, and since I often pull a trailer, it works just fine for me. Oh, and my parents live on top of the second biggest hill in the city I live in. A one mile uphill grade. Okay, so its a good motor, but what is the voltage and what is the wattage? And what is the load limit?

Great video with the needed details. The lighter weight GRIN hub = lower rotating mass and lower battery drain. Although it's a new bike this year, eventually I will replace my E-CELLS Super Monarch Crown front and rear motors with Grin Tech hub motors and controller. That they are made in Canada makes it just that much nicer. My folding solar "blanket" is a Canadian made 220 watt Off Grid TREK to charge my BLUETTI AC200 MAX power station that charges my two E-CELLS batteries when I'm car camping/hunting.

I like 2-strokes too. I once had a Japanese car that was a two-stroke that performed like an Aston Martin! Getting back to cyles : I want to do some extensive Touring on a Brompton folddown. Still in the Phase of deciding what, where and how; considering Regen Braking systems, thinking about Torque capacity of an E-bike motor for the Brompton and a whole lot more. I hope I can get a few hints and tips form this vlog, bearing in mind I am not young, have no smart sons who know everything, know nobody who can help BUT, I can learn reasonally fast, coming from a family where the men played with Engines.

I have been wondering why my ebike seems to lurch a little when starting off, it must be the slip fit torque arm not engaging tightly with the axle. Only 200 miles and the symtom has progressed. Great stuff.

I live in San Francisco CA and I have the 2 motor and never have problem pedal assistant for hill for fucking great 👍🏽 no problem the motor is from ebikeling .! 💯👍🏽👌🙏

We need this for automotive applications so any car can be transformed into electric...

You had me at 2-strokes.

You mention front mount,, anything on rear drive?

Hey ! Did you made your motor waterproof ?

Interresting. Why on earth not allowing air to go around the axle, cooling the stator ? Soak the stator into resin to waterproof it, and allow to pressure wash it. One step further make a turbine rotor to force air through it.

I use a similar motor to run my house, comes from a washing machine. You know they make the best generators.

A bit expensive, but the weight saving is very decent! My trike have a Cromotor, 75V with a custom Dropout that was actually laced at Holmes hobbies! Regen is fairly insane on this one, it can even lock up the wheel.

Thank u

What are the advantages of the all axle over the gmac motor. Love your presentation.

I've been building a 2wd Vector Typhoon based ebike with that hub in the front, phaserunner as its controller and Marzocchi Monster holding it. cant wait to use the bike (which is going to be VERY soon) let me know if you want pics, great looking bike.

we are building bicycle trailers to explore the Baja outback. Our trailers will be powered with regen. The motor you are profiling looks perfect for us. We could use your expertise.....

I just purchased a hyper scorpion and I am having a lot of fun riding around LA. Looking forward to America made improvement for the cheap Chinese made parts.

Can these go on the rear wheel?

Thank you for saving me all lot of money

I have a Lectric 3.0 would one of these new motors work for my bike for extra power to climb Bay Area hills?

Please let me know is it waterproof motor

Considering the price I'm not sure who would want this other than someone wanting to do a trike conversion.

Can show more videos on ebikes pls.

I am making dual motor ,,,,just for fun.bafang hub motors front and back.

I ride a home built trike. I'm handicapped. Im interested!

where in canada are you? also is this what you would get for a electric scooter? specifically a dualtron.. i want to upgrade my motors for more power (i have it almost running on vesc now haha **almost)

Great product 👍 Why are they only making front wheel motors?

I hope Grin makes a rear version of the All Axle.

BTW, I have a GRIN torque arm on my rear motor. Nothing GRiN makes fits my odd, heavy duty front fork drop outs.

I’m running a front 9C motor on my conversion ebike. (44V hand assembled battery, old school mtb, 26 in wheels, 35A controller) I would have loved to get one of these Grin hubs but it was not in my budget. Your advice on a torque arm is good, I have two on my bike.

Good video and I agree, Grin Tech Rocks :).

Awesome stuff brother. 😇🌎💫

I checked out the site, man those are redicoulisly high prices for only 500w kits. Bafang has 1500w for those prices.

Fantastic video I am looking for a recommendation, I am looking for a hub motor or and mid-drive. That will work on my Invacare top-end hand cycle. reverse is better

I am still trying to figure out how to get a Grin wheel for my coaster brake flat track bikes. I have skip tooth sprockets on pedals and 115mm drop outs not cassette friendly. LOL! My CWC 1953 Roadmaster front drop outs have not distorted in 1000km and several 30kph speed bump hits. I will machine a brace now to strap to the fork leg, American steel way better than alloy.

Looking to use a hub motor on a trike for steadi cam work. Need to be able to set the speed and also reverse the trike. Any suggestions ?

Interesting stuff, thank you for sharing. I looked through the rest of your videos and couldn't find any follow up to downhill hubdrive bike? I'm interested in making an hub drive 24in mtb, any direction would be appreciated.

Would you recommend waterproofing/waterresisting this motor?

Mixing The the metals add acid water electrolysis????

What's name of this motor? Because link to the motor from grin website is broken. Maybe knowing name will able to search on their website...

Thanks for the review, I see it this review was made a couple of years ago do you still feel the same about the hub? I'm considering building and e-bike and currently looking for a hub.

Planetary gearbox inside that space would be slick

So I'm in the States and I have a worry that this may be the reason but I tried to activating the link and going to the website you suggested for these wheels, sorry hubs, and I got a non-existent page error. Was the page just down or is there another reason why I couldn't access the web page?

Thanks, looks a good refinement of a direct drive hub motor, I would prefer a geared hub, but I know this is not everyones preference.

I brought a moto tech 350 w 36v I had to change the front tire actually still the process little did I know the wires to the motor are now showing but seem to be fine ... my question is do I need a new Hub or is my motor still good?

The Heinzmann RN 111 is even better. It is an oil-cooled geared hub motor from Germany. But it is more expensive.

Hey John, I'm trying to electrify a recumbent Delta Trike, the Sun EZ-3 USX HD (two wheels in the back, one in front). It needs to be really fast in that I will be using it for BikeJoring (riding with the Dogs). Can you, or would you, put two of the rear hub motors on the trike or would you use the X1 Pro Gen 2 or Stealth? Of course, bikejoring (dryland mushing) is all done on dirt. Let me know your thoughts, thanks in advance.

Hay plez do a video of your mounting 2 or 3 motors on a bike I'm trying and I'm just lost I'm using a ancheer eb004 (city commuter )

anyone running this on 72v and high ah and also can this motor handle going to 60mph easy without overheating and what not?

Any chance could u help me change my tire on my xp 2.0 I live in kirksville Missouri I'd be happy too bring it buy its the back tire you could do it for content on the channel

Are you going to do any reviews of their new v3 all-axle motors?

i have a 3000w hub motor and i NEED torque arms i went to a laser shop and let them cut out custom torque arms 8mm stainless steel works perfect! and the nuts i tighten with a torque key to 40nm. but i would love to have a thru axle motor but i didnt find a 12*135mm motor only 12*142..

Thanks John! Random question: I have a 48V battery and a 48V controller. What would happen if I ran a 60V hub motor on this otherwise 48V system?

You got to watch these hub motor repair ppl, guy wanted to charge me hundreds pounds to change my hub motor, brought 1 off Amazon put it in myself simple no drama 💋💯👍 UK 💋💯👍

Wattage, voltage and max speed would have been nice.

Let's do a cyclekart build with these!

Statorade? Hello???

would it be feasible to use a hub motor on rollerblads?

The wirer coming out of the rims what are they
